When erratum 1319367 is being worked around, special care must
be taken not to allow the page table walker to populate TLBs
while we have the stage-2 translation enabled (which would otherwise
result in a bizare mix of the host S1 and the guest S2).
We enforce this by setting TCR_EL1.EPD{0,1} before restoring the S2
configuration, and clear the same bits after having disabled S2.
